* x86, intel_txt: Factor out the code for S3 setupH. Peter Anvin2009-08-14
| | | | | | | | | | | | S3 sleep requires special setup in tboot. However, the data structures needed to do such setup are only available if CONFIG_ACPI_SLEEP is enabled. Abstract them out as much as possible, so we can have a single tboot_setup_sleep() which either is a proper implementation or a stub which simply calls BUG(). Signed-off-by: H.

* x86, intel_txt: Intel TXT Sx shutdown supportJoseph Cihula2009-07-21
| | | | | | | | | | | | | | | | | | | | | | | Support for graceful handling of sleep states (S3/S4/S5) after an Intel(R) TXT launch. Without this patch, attempting to place the system in one of the ACPI sleep states (S3/S4/S5) will cause the TXT hardware to treat this as an attack and will cause a system reset, with memory locked. Not only may the subsequent memory scrub take some time, but the platform will be unable to enter the requested power state. This patch calls back into the tboot so that it may properly and securely clean up system state and clear the secrets-in-memory flag, after which it will place the system into the requested sleep state using ACPI information passed by the kernel. arch/x86/kernel/smpboot.c | 2 ++ drivers/acpi/acpica/hwsleep.c | 3 +++ kernel/cpu.c | 7 ++++++- 3 files changed, 11 insertions(+), 1 deletion(-) Signed-off-by: Joseph Cihula <joseph.cihula@intel.com> Signed-off-by: Shane Wang <shane.wang@intel.com> Signed-off-by: H.

* x86, intel_txt: Intel TXT reboot/halt shutdown supportJoseph Cihula2009-07-21
| | | | | | | | | | | | | | | | | | | | | | | | Support for graceful handling of kernel reboots after an Intel(R) TXT launch. Without this patch, attempting to reboot or halt the system will cause the TXT hardware to lock memory upon system restart because the secrets-in-memory flag that was set on launch was never cleared. This will in turn cause BIOS to execute a TXT Authenticated Code Module (ACM) that will scrub all of memory and then unlock it. Depending on the amount of memory in the system and its type, this may take some time. This patch creates a 1:1 address mapping to the tboot module and then calls back into tboot so that it may properly and securely clean up system state and clear the secrets-in-memory flag. When it has completed these steps, the tboot module will reboot or halt the system. arch/x86/kernel/reboot.c | 8 ++++++++ init/main.c | 3 +++ 2 files changed, 11 insertions(+) Signed-off-by: Joseph Cihula <joseph.cihula@intel.com> Signed-off-by: Shane Wang <shane.wang@intel.com> Signed-off-by: H.

* x86, intel_txt: Intel TXT boot supportJoseph Cihula2009-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds kernel configuration and boot support for Intel Trusted Execution Technology (Intel TXT). Intel's technology for safer computing, Intel Trusted Execution Technology (Intel TXT), defines platform-level enhancements that provide the building blocks for creating trusted platforms. Intel TXT was formerly known by the code name LaGrande Technology (LT). Intel TXT in Brief: o Provides dynamic root of trust for measurement (DRTM) o Data protection in case of improper shutdown o Measurement and verification of launched environment Intel TXT is part of the vPro(TM) brand and is also available some non-vPro systems. It is currently available on desktop systems based on the Q35, X38, Q45, and Q43 Express chipsets (e.g. Dell Optiplex 755, HP dc7800, etc.) and mobile systems based on the GM45, PM45, and GS45 Express chipsets. For more information, see http://www.intel.com/technology/security/. This site also has a link to the Intel TXT MLE Developers Manual, which has been updated for the new released platforms. A much more complete description of how these patches support TXT, how to configure a system for it, etc. is in the Documentation/intel_txt.txt file in this patch. This patch provides the TXT support routines for complete functionality, documentation for TXT support and for the changes to the boot_params structure, and boot detection of a TXT launch. Attempts to shutdown (reboot, Sx) the system will result in platform resets; subsequent patches will support these shutdown modes properly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BSS section macros in vmlinux.lds.h currently place the .sbss input section outside the bounds of [__bss_start, __bss_end]. On all architectures except for microblaze that handle both .sbss and __bss_start/__bss_end, this is wrong: the .sbss input section is within the range [__bss_start, __bss_end]. Relatedly, the example code at the top of the file actually has __bss_start/__bss_end defined twice; I believe the right fix here is to define them in the BSS_SECTION macro but not in the BSS macro. Another problem with the current macros is that several architectures have an ALIGN(4) or some other small number just before __bss_stop in their linker scripts. The BSS_SECTION macro currently hardcodes this to 4; while it should really be an argument. It also ignores its sbss_align argument; fix that. mn10300 is the only user at present of any of the macros touched by this patch. It looks like mn10300 actually was incorrectly converted to use the new BSS() macro (the alignment of 4 prior to conversion was a __bss_stop alignment, but the argument to the BSS macro is a start alignment). So fix this as well. I'd like acks from Sam and David on this one. Also CCing Paul, since he has a patch from me which will need to be updated to use BSS_SECTION(0, PAGE_SIZE, 4) once this gets merged.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Blackfin SMP, a per-cpu loops_per_jiffy is pointless since both cores always run at the same CCLK. In addition, the current implementation has flaws since the main consumer for loops_per_jiffy (asm/delay.h) uses the global kernel loops_per_jiffy and not the per_cpu one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we need to relocate the attached filesystem with the uClinux MTD map (to handle some anomalies), we need to know its real filesize. If we boot a kernel without a filesystem actually attached, we end up blindly reading and copying garbage (since there is no magic value to detect validity). Often times this results in an early crash and no output. So add a few basic sanity checks before operating on things to catch the majority of cases.
